dbo user

Hi Gurus,

I recently inherited an ASE database that hasn't received any love from whom ever was maintaining the system, the current state of the database is equal to a badly written code, no proper indexation, to name a few.

I been poking around and found one scenario where the "dbo" is assigned to a different user with a 'sa_role', is this a norm?

Also, further to my investigation, I discover that all users have the 'sa_role'.

My Question is
1. Should a normal user have 'sa_role' assigned to them, is this norm?
2. If #1 is not "standard" what is the quickest way for me to extract all user/login and amend the user role.
2. What is the standard role for the 'dbo' user?


Apology if my question are rather noobish, I am not a DBA but got nominated to investigate this environment that is running very slow.

System Details
O.S: Windows NT
ASE version: ASE 11.5


Appreciate all your help.

Regards
Alvin
